Inclusion Criteria
  • Baseline with a total body weight of 10 kg or higher at screening and a diagnosis of systemic juvenile idiopathic arthritis (sJIA) according to International League of Associations for Rheumatology (ILAR) criteria for at least 6 weeks prior to Screening, with onset prior to 16 years old, and meet the following conditions: -- Must have active sJIA with at least 2 active joints at Screening and Baseline, fever more than 38 Celsius for any out of 14 consecutive days before the Screening Visit, and an erythrocyte sedimentation rate (ESR) or high-sensitivity C-reactive protein (hsCRP) > 1.5 x upper limit of normal (ULN) at Screening. OR At least 5 active joints at Screening and Baseline and an ESR or hsCRP > 1.5 x ULN at Screening. -- Must have inadequate response to previous treatment with nonsteroidal anti-inflammatory drugs and systemic glucocorticoids, as judged by the investigator. -- For Cohort 1, participants must not have had previous treatment with any IL-6 inhibitor. For Cohort 2, participants must have an intolerance or inadequate response to an IL-6 inhibitor as judged by the investigator. Note: For Cohort 1, participants must be ages 2 to < 18 years old in countries where subcutaneous tocilizumab is not approved for sJIA.
Exclusion Criteria
  • Must have any type of juvenile idiopathic arthritis (JIA), other than sJIA, as defined by the ILAR criteria, and must not have a history or presence of any other autoimmune inflammatory condition other than sJIA.
  • Must have uncontrolled severe systemic disease and/or impeding or active macrophage activation syndrome within 3 months prior to Baseline.
